Missing Protection Against Hardware Reverse Engineering Using Integrated Circuit (IC) Imaging Techniques

Description

Information stored in hardware may be recovered by an attacker with the capability to capture and analyze images of the integrated circuit using techniques such as scanning electron microscopy.

The physical structure of a device, viewed at high enough magnification, can reveal the information stored inside. Typical steps in IC reverse engineering involve removing the chip packaging (decapsulation) then using various imaging techniques ranging from high resolution x-ray microscopy to invasive techniques involving removing IC layers and imaging each layer using a scanning electron microscope. The goal of such activities is to recover secret keys, unique device identifiers, and proprietary code and circuit designs embedded in hardware that the attacker has been unsuccessful at accessing through other means. These secrets may be stored in non-volatile memory or in the circuit netlist. Memory technologies such as masked ROM allow easier to extraction of secrets than One-time Programmable (OTP) memory.

Common Consequences

Scope: Confidentiality

Impact: Varies by Context

Notes: A common goal of malicious actors who reverse engineer ICs is to produce and sell counterfeit versions of the IC.
